Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Analisis Keamanan Jaringan Wi-Fi Pada SMKN 1 Kota Jantho Menggunakan Metode Vulnerability Assessment
No full textKeamanan jaringan nirkabel merupakan aspek penting yang harus dijaga, terutama pada lingkungan pendidikan yang memanfaatkan Wi-Fi sebagai sarana pendukung proses pembelajaran. Penelitian ini bertujuan untuk melakukan penilaian kerentanan pada jaringan Wi-Fi SMKN 1 Kota Jantho dengan menggunakan dua aplikasi utama, yaitu Kismet dan Airodump-ng . Kismet adalah aplikasi sumber terbuka yang mampu mendeteksi, menyatukan, dan menganalisis jaringan Wi-Fi secara pasif, menampilkan informasi seperti SSID, BSSID , jenis enkripsi, kekuatan sinyal, serta perangkat klien yang terhubung. Sementara itu, Airodump-ng merupakan bagian dari paket Aircrack-ng yang berfungsi menyatukan lalu lintas jaringan secara real-time dan menangkap data, termasuk handshake WPA/WPA2 , untuk analisis keamanan lebih lanjut. Metodologi penelitian meliputi tahap instalasi aplikasi pada sistem operasi Kali Linux , konfigurasi antarmuka nirkabel pada mode monitor ( wlan0 ), serta proses pemindaian jaringan untuk mengidentifikasi potensi kerentanan. Data yang diperoleh dari kedua aplikasi kemudian dianalisis dan diklasifikasikan berdasarkan standar CVSS ( Common Vulnerability Scoring System ) guna menentukan tingkat keparahan risiko. Selain pemindaian, dilakukan simulasi serangan ringan berupa serangan deauthentication untuk menguji respons jaringan terhadap upaya pemutusan koneksi klien. Hasil penelitian menunjukkan bahwa Kismet memberikan informasi yang lebih terstruktur dan mudah dianalisis dibandingkan Airodump-ng , sehingga lebih disukai oleh sebagian besar responden, termasuk guru. Namun, Airodump-ng tetap unggul dalam pemantauan cepat dan penangkapan jabat tangan untuk pengujian keamanan kata sandi. Berdasarkan temuan ini, penggunaan kedua aplikasi secara kombinasi direkomendasikan untuk memperoleh gambaran keamanan jaringan yang lebih komprehensif dan mendukung strategi mitigasi yang efektif.

Wi-Fi Network Security Analysis At SMKN 1 Kota Jantho Using The Vulnerability Assessment Method
Wi-Fi network security in educational environments plays a crucial role in maintaining data confidentiality and integrity. This study aims to analyze the security level of the Wi-Fi network at SMKN 1 Kota Jantho using a vulnerability assessment approach based on open-source applications, namely Kismet and Airodump-ng. Kismet was employed to detect and passively monitor wireless networks, while Airodump-ng was used to capture WPA/WPA2 handshakes and observe network traffic in real-time. The collected data were evaluated using the Common Vulnerability Scoring System (CVSS) to determine risk levels, and a deauthentication attack simulation was conducted to assess the network’s resilience. The results revealed several vulnerabilities with an average CVSS score in the High category (7.58), including the use of weak encryption (WEP), insecure management services (Telnet), and the potential for rogue access points. Compared to previous studies, this research provides a practical contribution by offering a simpler, cost-effective, and applicable approach to improving Wi-Fi security in schools without requiring specialized hardware or licensed software. These findings highlight that the combination of Kismet and Airodump-ng can serve as an effective solution for mapping vulnerabilities and supporting security mitigation strategies in educational environments.

Optimasi Keamanan dan Penggunaan Bandwidth pada Jaringan Internet Menggunakan Proxy Server di CV. Peut Sagoe Design
No full textKeamanan jaringan dan efisiensi penggunaan bandwidth merupakan faktor kunci bagi perusahaan yang bergantung pada internet untuk operasional harian. CV. Peut Sagoe Design, sebuah perusahaan arsitektur dan rekayasa teknik, menghadapi masalah pemborosan bandwidth akibat akses non-produktif serta risiko keamanan karena kurangnya kontrol lalu lintas data. Penelitian ini bertujuan untuk menganalisis efektivitas penerapan proxy server dalam meningkatkan keamanan jaringan dan mengoptimalkan penggunaan bandwidth. Metode penelitian terapan dengan pendekatan kuantitatif digunakan, melibatkan observasi, wawancara dengan 10 karyawan dan 2 staf IT, serta pengukuran parameter jaringan menggunakan PRTG Network Monitor dan Wireshark. Implementasi dilakukan dengan Squid Proxy pada Ubuntu Server 22.04, dikonfigurasi dengan caching, filtering, dan access control list (ACL). Data dikumpulkan sebelum dan sesudah implementasi untuk membandingkan rata-rata penggunaan bandwidth, kecepatan unduh/unggah, dan latensi. Hasil menunjukkan penurunan penggunaan bandwidth sebesar 42%, peningkatan kecepatan unduh sebesar 38,8%, penurunan latensi sebesar 47,7%, dan peningkatan stabilitas jaringan. Uji statistik paired t-test menghasilkan nilai p = 0,003 (< 0,05), menunjukkan perbedaan signifikan sebelum dan sesudah implementasi. Wawancara mengungkapkan akses cloud yang lebih cepat, waktu unggah/unduh yang lebih singkat, dan berkurangnya distraksi kerja akibat pembatasan akses. Penerapan proxy server terbukti efektif dalam meningkatkan efisiensi jaringan, keamanan data, dan produktivitas kerja.

Optimizing Security and Bandwidth Usage on Internet Networks Using a Proxy Server at CV. Peut Sagoe Design
Network security and efficient bandwidth usage are crucial factors for companies that rely on the internet for daily operations. CV. Peut Sagoe Design, an architecture and engineering firm, faces bandwidth wastage due to unproductive access and security risks due to lack of data traffic control. This study aims to analyze the effectiveness of implementing a proxy server in improving network security and optimizing bandwidth usage. The study uses an applied method with a quantitative approach, involving observation, interviews with 10 employees and 2 IT staff, and network parameter measurements using PRTG Network Monitor and Wireshark. Implementation was carried out using Squid Proxy on Ubuntu Server 22.04 configured with caching, filtering, and access control lists (ACLs). Data before and after implementation were compared to assess changes in average bandwidth usage, download/upload speeds, and latency. The results show a 42% decrease in bandwidth usage, a 38.8% increase in download speed, a 47.7% decrease in latency, and an increase in network stability. A paired t-test yielded a p-value of 0.003 (<0.05), proving a significant difference before and after implementation. Interviews revealed increased cloud access speeds, shorter upload/download times, and reduced work distractions due to access restrictions. From a security perspective, before the proxy was implemented, data traffic was vulnerable to information leaks and malware attacks. After implementation, these risks were successfully mitigated through filtering, ACLs, and activity logging that supports digital forensic analysis. Thus, the proxy server implementation proved effective in optimizing bandwidth, improving network security, and supporting company productivity.

Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
